Charles Wysong who Susan Boomershine

I am searching for the parents of my great-great grandfather Charles Wysong (1866-1913 Preble County, Ohio.) He married Susan Boomershine who died in 1908. My Charles had three children... Maude (married a Loy and ended up in FL) Ward (1889-1911) and my g-grandfather Joseph who married a woman named Rosella.

I can only find Charles in the 1900 census of Preble co, and in a mention in the Boomershine history of his wife's family.

Its pretty safe to assume he is a descendant of Valentine because of the area he lived in, but I can find absolutely no mention of him in any of the Valentine genealogy I have found.
